Try with this formula :

 

Status = 
IF( ISBLANK(DateAdd(Guests[Dates];-1;DAY));"First Day";
	IF ( ISBLANK(DateAdd(Guests[Dates];1;DAY) ) ; "Last Day" ; "Middle Day" ) )

Hi, try with this calculated column:

 

Day =
VAR StayDate = Table1[StayDate] - 1
VAR StayDate_plus1 = Table1[StayDate] + 1
RETURN
    IF (
        COUNTROWS (
            FILTER (
                Table1;
                Table1[StayDate] = StayDate
                    && Table1[GuesID] = EARLIER ( Table1[GuesID] )
            )
        )
            < 1;
        "First";
        IF (
            COUNTROWS (
                FILTER (
                    Table1;
                    Table1[StayDate] = StayDate_plus1
                        && Table1[GuesID] = EARLIER ( Table1[GuesID] )
                )
            )
                < 1;
            "Last";
            "Middle"
        )
    )

yes

Hello,

 

I created this table :

Created this column :

Status = 
IF( Guests[Dates]=CALCULATE ( MINX( Guests; Guests[Dates]) ; ALLEXCEPT ( Guests ; Guests[Guests] ) );"First Day";
	IF( Guests[Dates]=CALCULATE ( MAXX( Guests; Guests[Dates]) ; ALLEXCEPT ( Guests ; Guests[Guests] ) ); "Last Day"
	;"Middle Day" ))

The result :

I hope this will help

 

 

All of those days you provided should actually be listed as first days becuase the previous day they did not stay with us. 

 

if the guest stays with us on the 1st, 2nd and 3rd the 1st should be a first day the 2nd a Middle and the 3rd day a last.

 

Then if the same guest stays with us on the 5th-6th the 5th should be a new first day then the 6th a last day.

 

Does that make sense?

 

Try with this formula :

 

Status = 
IF( ISBLANK(DateAdd(Guests[Dates];-1;DAY));"First Day";
	IF ( ISBLANK(DateAdd(Guests[Dates];1;DAY) ) ; "Last Day" ; "Middle Day" ) )

Amazing thank you!

Hi, there is a issue in the formula when you have contiguous dates in different GuestID.

you are right 😞 . I saw this when I applied to my larger dataset, any way to work around?

                )
            )
                < 1;
            "Last";
            "Middle"
        )
    )
